Abstract

The geometry of the point focusing monochromator is described, and the instrument's uses in connection with low angle diffraction studies are outlined. A careful determination of the particle size of latex spheres by studies of the associated low angle diffraction pattern is made, and an experiment to determine the sensitivity of this particle size to external pressure is described. The results of an experiment in which the monochromator is used to obtain important information on the existence and nature of the collagen molecule are given. A technique for finding the size of particles whose shape is reasonably approximated by two spheroids is given, and the technique is applied to the size determination of bacteriophage type T-4. Improvements in the instrument are discussed and several suggestions for further applications are mentioned.
